What combination of different substances that remain the same individual substances and can be separated by physical means?
it means that substances like solids liquids or gas can be departed by active movement.
You have two solid substances that look the same What measurements would you take and which tests would you perform to determine whether they actually are the same?
- chemical analysis of these substances - determination of some physical properties
What type of change is teeth crushing food physical or chemical?
It is physical. The tooth is broken into smaller pieces, but the pieces are still made of the same substances.
Is NaCl dissolved in a jar leaving salt behind a chemical change or a physical change?
When NaCl is dissolved in a jar, it undergoes a physical change. This is because the chemical composition of NaCl remains the same, but its physical state changes from a solid to a liquid solution. The salt can be reclaimed by evaporating the liquid and it would still have the same chemical properties as the original NaCl.
Is the preparation of sugar solution physical change?
Yes. Both the sugar and the water (or other solvent) remain the same chemicals. Since no chemical change occurs during creation of the solution, it is a physical change.
What are the differences between solutions and mixtures?
A *solution* is a mixture of substances that are blended so completely that the mixture looks the same everywhere while a *mixture* is a physical combination of two or more substances that are blended together without forming new substances.
Is urine a compound?
Urine is a homogeneous mixture - all components are in the same physical state as an aqueous solution.
How is the mixture the same as a solution?
in both, substances mix together
How is a mixture same as a solution?

What happens when the concentration of dissolved substances is in the same in both the cell and the solution in which it is placed?
Isotonic solution
Is mixing two cheeses in a bowl a physical or chemical change?
No. The cheese is still cheese, it's just in pieces now.
What is it called if the concentration of dissolved substances will be the same in both the cell and the solution in which it is placed?
Homeostasis
Why is a solution classified as a mixture?
A solution contains a solvent and one or more solutes. It is classified as a mixture because when a substance is dissolved in another substance, the two substances are still the same substances, not having undergone any significant chemical change, they are just mixed together.
What are substances in which the composition is the same throughout?
If it is a pure substance, then it is a molecule or formula unit. If it is a mixture, it is a solution.
If a cell is placed in what solution the concentration of dissolved substances will be the same in both the cell and the solution in which it is placed?
Hypotonic :) good luck on plato :D
How physical properties and chemical properties are the same?
They both describe substances
What combination of different substances that remain the same individual substances and can be separated by physical means?
